Have read countless books trying to find simple explanation of various patterns somehow nothing went into my head. Here is my mundane take on some patterns.
Facade -> Think of Dispenser which allows you to buy various goodies
Adapter -> US Plugpoint Convertor
Observer -> Newspaper/Magazine subscription, you tell them your address and they send you latest issue once published
Visitor -> Weight Machine that tells weight of the person
Command -> Remote Control, the interface to switch between DVD mode or channel switch is same. The actual data is encapsulated
Strategy -> I am making a dish for which i want to grind something, can use Mixie or Stone. Both allow me to Grind, there by encapsulating the lower level detail.
Template-> A day has a fixed routine, morning, afternoon, evening and a night. How we spend it is upon us
